LDL1117S50R 詳細描述
Product Overview
The STMicroelectronics LDL1117S50R is a linear voltage regulator IC configured as a positive, fixed-output device with one regulator. It provides a 5V output at up to 1.2A and is specified for a maximum input voltage of 18V. The device uses a surface-mount SOT-223 package, listed as TO-261-4, TO-261AA, and has a 0.6V maximum dropout at 1.2A. Its protection set includes over current, over temperature, and under voltage lockout. The operating junction temperature range is -40°C to 125°C, and the quiescent current is 500 µA.
Key Features
- Positive fixed 5V output from a single linear regulator.
- Output current rating of 1.2A with 0.6V maximum dropout at 1.2A.
- Maximum input voltage of 18V and quiescent current of 500 µA.
- Protection features include over current, over temperature, and under voltage lockout (UVLO).
- Operating junction temperature range of -40°C to 125°C.
- Surface-mount SOT-223 package, listed as TO-261-4, TO-261AA.
- PSRR is specified as 87 dB ~ 65 dB from 120 Hz ~ 100 kHz.
Applications
- Board-level 5V rail regulation for control circuitry.
- Surface-mount regulator placement in assemblies that need a fixed 5V output at 1.2A.
- Power rails where PSRR from 120Hz to 100kHz is a design consideration.
- Regulator stages where over current, over temperature, and UVLO protection are required.
Design & Procurement Notes
When selecting LDL1117S50R, verify that the input does not exceed 18V and that the load remains within 1.2A. The 0.6V dropout at 1.2A means the input must remain sufficiently above 5V under load, especially near the 125°C junction temperature limit. The SOT-223 package, listed as TO-261-4 and TO-261AA, is surface mount, so layout and thermal path should support the operating junction temperature range. The supplied protection features are over current, over temperature, and UVLO; supplied data do not specify output capacitor requirements, enable behavior, or thermal resistance. Confirm the Active lifecycle status and exact package before ordering.
